FIELD OF THE INVENTION

The present invention relates to transgenic soybean event MON87705 and plant parts and seed thereof. The event exhibits an oil composition comprising altered fatty acid levels. The invention also relates to methods for detecting the presence of soybean event in a biological sample, and provides nucleotide sequences that are capable of doing so.

BACKGROUND OF THE INVENTION

Soybean is an important crop and is a primary food source in many areas of the world. The methods of biotechnology have been applied to soybean for improvement of agronomic traits and the quality of the product. One such quality trait is a soybean oil comprising altered fatty acid levels.

It would be advantageous to be able to detect the presence of transgene/genomic DNA of a particular plant in order to determine whether progeny of a sexual cross contain the transgene/genomic DNA of interest. In addition, a method for detecting a particular plant would be helpful when complying with regulations requiring the pre-market approval and labeling of foods derived from the recombinant crop plants.

Soybean oils have been modified by various breeding methods to create benefits for specific markets. However, a soybean oil that is broadly beneficial to major soybean oil users such as consumers of salad oil, cooking oil and frying oil, and industrial markets such as biodiesel and biolube markets, is not available. Prior soybean oils were either too expensive or lacked an important food quality property such as oxidative stability, good fried food flavor or saturated fat content or an important biodiesel property such as appropriate nitric oxide emissions or cold tolerance or cold flow.

Soybean oil typically contains approximately 20% oleic acid. Oleic acid has one double bond, but is still relatively stable at high temperatures, and oils with high levels of oleic acid are suitable for cooking and other processes where heating is required. Recently, increased consumption of high oleic oils has been recommended, because oleic acid appears to lower blood levels of low density lipoproteins (“LDLs”) without affecting levels of high density lipoproteins (“HDLs”). However, some limitation of oleic acid levels is desirable, because when oleic acid is degraded at high temperatures, it creates negative flavor compounds and diminishes the positive flavors created by the oxidation of linoleic acid. Neff et al., JAOCS, 77:1303-1313 (2000); Warner et al., J. Agric. Food Chem. 49:899-905 (2001). It is thus preferable to use oils with oleic acid levels that are 65-85% or less by weight, in order to limit off-flavors in food applications such as frying oil and fried food. Other preferred oils have oleic acid levels that are greater than 55% by weight in order to improve oxidative stability.

For many oil applications, saturated fatty acid levels of less than 8% by weight or even less than about 2-3% by weight are desirable. Soybean oil typically contains about 16-20% saturated fatty acids: 13-16% palmitate and 3-4% stearate (see generally Gunstone et al., The Lipid Handbook, Chapman & Hall, London (1994)). Saturated fatty acids have high melting points which are undesirable in many applications. When used as a feedstock or fuel, saturated fatty acids cause clouding at low temperatures and confer poor cold flow properties such as pour points and cold filter plugging points to the fuel. Oil products containing low saturated fatty acid levels may be preferred by consumers and the food industry because they are perceived as healthier and/or may be labeled as “saturated fat free” in accordance with FDA guidelines. In addition, low saturate oils reduce or eliminate the need to winterize the oil for food applications such as salad oils. In biodiesel and lubricant applications oils with low saturated fatty acid levels confer improved cold flow properties and do not cloud at low temperatures.

Soybean lines that produce seed with mid-oleic and low saturate content would be desirable. Methods disclosed here enable production of soybean seeds that have oleic acid levels in the mid oleic range of 55-80% and saturated fatty acid levels of less than 8%.

The expression of foreign genes in plants is known to be influenced by their chromosomal position, perhaps due to chromatin structure (e.g., heterochromatin) or the proximity of transcriptional regulation elements (e.g., enhancers) close to the integration site (Weising et al., 1988 Ann. Rev. Genet 22:421-477). For this reason, it is often necessary to screen a large number of events in order to identify an event characterized by optimal expression of an introduced gene of interest. For example, it has been observed in plants and in other organisms that there may be wide variation in the levels of expression of an introduced gene among events. There may also be differences in spatial or temporal patterns of expression, for example, differences in the relative expression of a transgene in various plant tissues, that may not correspond to the patterns expected from transcriptional regulatory elements present in the introduced gene construct. For this reason, it is common to produce several hundred to several thousand different events and screen the events for a single event that has the desired transgene expression levels and patterns for commercial purposes. An event that has the desired levels or patterns of transgene expression is useful for introgressing the transgene into other genetic backgrounds by sexual outcrossing using conventional breeding methods. Progeny of such crosses maintain the transgene expression characteristics of the original transformant. This strategy is used to ensure reliable gene expression in a number of varieties that are suitably adapted to specific local growing conditions.

It is possible to detect the presence of a transgene by any well known nucleic acid detection method such as the polymerase chain reaction (PCR) or DNA hybridization using nucleic acid probes. These detection methods generally focus on frequently used genetic elements, such as promoters, terminators, marker genes, etc. As a result, such methods may not be useful for discriminating between different events, particularly those produced using the same DNA construct unless the sequence of chromosomal DNA adjacent to the inserted DNA (“flanking DNA”) is known. An event-specific PCR assay is discussed, for example, by Taverniers et al. (J. Agric. Food Chem., 53: 3041-3052, 2005) in which an event-specific tracing system for transgenic maize lines Bt11, Bt176, and GA21 and for canola event GT73 is demonstrated. In this study, event-specific primers and probes were designed based upon the sequences of the genome/transgene junctions for each event. Transgenic plant event-specific DNA detection methods have also been described in U.S. Pat. Nos. 6,893,826; 6,825,400; 6,740,488; 6,733,974; 6,689,880; 6,900,014 and 6,818,807.

This invention relates to the transgenic soybean (Glycine max) plant MON87705 with an oil composition comprising altered fatty acid levels and to the DNA construct of soybean plant MON87705 and the detection of the transgene/genomic insertion region in soybean MON87705 and progeny thereof.

SEQ ID NO: 14—Probe PB10335 used to determine zygosity of MON87705 events. This probe is a VIC™-labeled synthetic oligonucloetide whose sequence corresponds to a region of the wild-type genomic DNA. A PCR amplicon produced using primers SQ21928 and SQ21905 causes the release of a fluorescent signal using probe PB10335 which is positive for the presence of the wild-type allele in a zygosity assay for event MON87705. This sequence corresponds to positions 12 to 31 of the forty base pair wild type sequence listed as SEQ ID NO: 17 which was lost in the generation of the MON87705 event.

SEQ ID NO: 15—Primer SQ21905 used to determine zygosity of MON87705 events. Detection of a PCR amplicon using 6FAM™-labeled Probe PB10335 and primers SQ21928 and SQ21905 is positive for presence of wild type in a zygosity assay. Sixteen base pairs of sequence corresponds to positions 1037 to 1052 of SEQ ID NO: 6 while this primer continues ten base pairs into the forty base pair region of wild type sequence listed as SEQ ID NO: 16 which was lost in the generation of the MON87705 event.

SEQ ID NO: 16—Forty base pair sequence that was lost at the junction of the tandem repeat sequence (SEQ ID NO: 17) and the 5′ genomic sequences. This sequence is found in the wild type and would have been located between base pair 1052 and 1053 in SEQ ID NO: 6 had it not been lost during the generation of the MON87705 event. Due to the duplication of the genomic sequence upon the generation of the MON87705 event, the terminal twelve bases of sequence is also located at position 10670 to 10681 of SEQ ID NO: 6, but the remaining twenty eight base pairs are completely absent from the MON87705 event and therefore may be utilized to identify the wild type in an assay for zygosity.

SEQ ID NO: 17—This 2370 bp sequence is the portion of the wild type genomic sequences which was apparently duplicated upon generation of the MON87705 event. This region of duplication corresponds to position 1053 to 3422 and is nearly identical to position 10682 to 13051 of SEQ ID NO: 6. Duplicate Genomewalker™ based clones of this region shared two mismatches in the repeat located on the 5′ end of the insert when compared to the 3′ end and the soy genomic sequence. The two altered bases in the 5′ repeat, along with the deletion found on the 5′ end of the duplication (SEQ ID NO:16) leads us to the additional that the tandem sequences corresponding to position 1053 to 3422 is the newly generated sequence while the sequence corresponding to position 10682 to 13051 is the original wild type sequence.

SEQ ID NO: 18—This 106 bp sequence spans the right border to right border junction generated upon the co-integration of the two pMON95829 T-DNAs to yield event MON87705. It starts and ends with twenty bases of the suppression target FATB, one from each arm of the inverted repeat, and contains residual border sequences and inserted sequences generated in the integration of the sequences found in the MON87705 event. This sequence corresponds to position 9230 to 9335 of SEQ ID NO: 6. Although this sequence lies within the suppression cassette, due to the random nature of the assembly of the two T-DNAs in vivo, the sequence combination is unique to the MON87705 event.

SEQ ID NO: 19—Primer 24894 used in the secondary (nested) PCR in combination with AP2 for amplification of the Genomewalker™-derived 5′ flank extension. This sequence corresponds to position 3722 to 3748 of SEQ ID NO: 6.

SEQ ID NO: 20—Primer 24895 used in the primary PCR in combination with AP1 for amplification of the Genomewalker™-derived 5′ flank extension. This sequence corresponds to position 3798 to 3827 of SEQ ID NO: 6.

DETAILED DESCRIPTION

The following definitions and methods are provided to better define the present invention and to guide those of ordinary skill in the art in the practice of the present invention. Unless otherwise noted, terms are to be understood according to conventional usage by those of ordinary skill in the relevant art. Definitions of common terms in molecular biology may also be found in Rieger et al., Glossary of Genetics: Classical and Molecular, 5th edition, Springer-Verlag: New York, 1991; and Lewin, Genes V, Oxford University Press: New York, 1994.

As used herein, the term “soybean” means Glycine max and includes all plant varieties that can be bred with soybean, including wild soybean species as well as those plants belonging to Glycine soja that permit breeding between species.

“Glyphosate” refers to N-phosphonomethylglycine and its salts. N-phosphonomethylglycine is a well-known herbicide that has activity on a broad spectrum of plant species.

“Desaturase” refers to a polypeptide that can desaturate or catalyze formation of a double bond between consecutive carbons of one or more fatty acids to produce a mono- or poly-unsaturated fatty acid or a precursor thereof. Of particular interest are polypeptides that can catalyze the conversion of oleic acid to linoleic acid or linoleic acid to α-linolenic acid, which includes enzymes which desaturate at the 12 or 15 positions. Considerations for choosing a specific polypeptide having desaturase activity include, but are not limited to, the pH optimum of the polypeptide, whether the polypeptide is a rate limiting enzyme or a component thereof, whether the desaturase used is essential for synthesis of a desired PUFA, and/or whether a co-factor is required by the polypeptide. The expressed polypeptide preferably has characteristics that are compatible with the biochemical environment of its location in the host cell. For example, the polypeptide may have to compete for substrate(s). An endogenous desaturase may also be the target of gene suppression.

“Thioesterase” refers to a polypeptide that can hydrolyze the thioester bond of molecules (splitting of an ester bond into acid and alcohol, in the presence of water) specifically at a thiol group. Of particular interest are polypeptides that can catalyze the hydrolysis of the thioester bond contained in acyl-acyl-carrier proteins (acyl-ACP), especially stearoyl- and palmitoyl-ACP substrates. Such hydrolysis produces a free fatty acid and ACP, thereby terminating the fatty acid biosynthesis of plants located in the plastid and readies the fatty acid for export to the cytoplasm. Considerations for choosing a specific polypeptide having thioesterase activity include, but are not limited to, the pH optimum of the polypeptide, whether the polypeptide is a rate limiting enzyme or a component thereof and whether the thioesterase used is essential for increased production of saturated fatty acids. The expressed polypeptide preferably has characteristics that are compatible with the biochemical environment of its location in the host cell. For example, the polypeptide may have to compete for substrate(s). An endogenous thioesterase may also be the target of gene suppression.

A “commodity product” refers to any product which is comprised of material derived from soybean or soybean oil and is sold to consumers. Processed soybeans are the largest source of protein feed and vegetable oil in the world. The soybean plant MON87705 can be used to manufacture commodities typically acquired from soy. Soybeans of MON87705 can be processed into meal, flour, or oil as well as be used as a protein or oil source in animal feeds for both terrestrial and aquatic animals. Soybeans and soybean oils from MON87705 can be used in the manufacture of many different products, not limited to, nontoxic plastics, printing inks, lubricants, waxes, hydraulic fluids, electric transformer fluids, solvents, cosmetics, and hair care products. Soybeans and oils of MON87705 can be suitable for use in a variety of soyfoods made from whole soybeans, such as soymilk, soy nut butter, natto, and tempeh, and soyfoods made from processed soybeans and soybean oil, including soybean meal, soy flour, soy protein concentrate, soy protein isolates, texturized soy protein concentrate, hydrolyzed soy protein, whipped topping, cooking oil, salad oil, shortening, and lecithin. Whole soybeans are also edible, and are typically sold to consumers raw, roasted, or as edamamé. Soymilk, which is typically produced by soaking and grinding whole soybeans, may be consumed without other processing, spray-dried, or processed to form soy yogurt, soy cheese, tofu, or yuba.

Oils of MON87705 can be used to make biodiesel. The use of biodiesel in conventional diesel engines results in substantial reductions of pollutants such as sulfates, carbon monoxide, and particulates compared to petroleum diesel fuel, and use in school buses can greatly reduce exposure to toxic diesel exhaust. Biodiesel is typically obtained by extracting, filtering and refining soybean oil to remove free fats and phospholipids, and then transesterifying the oil with methanol to form methyl esters of the fatty acids (see for example U.S. Pat. No. 5,891,203). The resultant soy methyl esters are commonly referred to as “biodiesel.” The oil derived from MON87705 may also be used as a diesel fuel without the formation of methyl esters, such as, for example, by mixing acetals with the oil (see for example U.S. Pat. No. 6,013,114). The seeds of MON87705 used to make said oils can be identified by the methods of the present invention. It is expected that purified oil from MON87705 event seeds or mixtures of seeds some or all of which are MON87705 will have relatively no DNA available for testing. However, the seeds from which the oils are extracted can be characterized with the method of the present invention to identify the presence of the MON87705 event within the population of seeds used to make said oils. Also, plant waste from the process used to make said oils can be used in the methods of the present invention to identify the presence of MON87705 events within a mixture of seeds processed to make said oils. Likewise, plant debris left after making a commodity product, or left behind following harvest of the soybean seed, can be characterized by the methods of the present invention to identify MON87705 events within the raw materials used to make said commodity products.

The present invention also includes a blended or non-blended soybean oil of MON87705. Such oil may be blended with other oils. In a preferred embodiment, the oil produced from plants of the present invention or generated by a method of the present invention constitutes greater than 0.5%, 1%, 5%, 10%, 25%, 50%, 75% or 90% by volume or weight of the oil component of any product. In another embodiment, the oil preparation may be blended and can constitute greater than 10%, 25%, 35%, 50% or 75% of the blend by volume. Oil produced from a plant of the present invention can be admixed with one or more organic solvents or petroleum distillates.

A transgenic “event” is produced by transformation of plant cells with heterologous DNA, i.e., a nucleic acid construct that includes a transgene of interest, regeneration of a population of plants resulting from the insertion of the transgene into the genome of the plant, and selection of a particular plant characterized by insertion into a particular genome location. The term “event” refers to the original transformant and progeny of the transformant that include the heterologous DNA. The term “event” also refers to progeny produced by a sexual outcross between the transformant and another variety, wherein the progeny comprises the heterologous DNA. Even after repeated back-crossing to a recurrent parent, the inserted DNA and flanking DNA from the original transformation may be present in the progeny of the cross at the same chromosomal location. The term “event” also refers to DNA from the original transformant comprising the inserted DNA and flanking genomic sequence immediately adjacent to the inserted DNA that would be expected to be transferred to a progeny that receives inserted DNA including the transgene of interest as the result of a sexual cross of one parental line that includes the inserted DNA (e.g., the original transformant and progeny resulting from selfing) and a parental line that does not contain the inserted DNA. The present invention relates to the event MON87705 DNA, plant cells, tissues, seeds and processed products derived from MON87705.

It is also to be understood that two different transgenic plants, or a transgenic plant and a wild-type plant, can also be mated to produce offspring that contain two independently segregating added, exogenous genes. The offspring can be homozygous or heterozygous for the genes. Selfing of appropriate progeny can produce plants that are homozygous for both added, exogenous genes. Back-crossing to a parental plant and out-crossing with a non-transgenic plant are also contemplated, as is vegetative propagation. Descriptions of other breeding methods that are commonly used for different traits and crops can be found in one of several references, e.g., Fehr, in Breeding Methods for Cultivar Development, Wilcox J. ed., American Society of Agronomy, Madison Wis. (1987).

As used herein when referring to an “isolated DNA molecule”, it is intended that the DNA molecule be one that is present, alone or in combination with other compositions, but not within its natural environment. For example, a coding sequence, intron sequence, untranslated leader sequence, promoter sequence, transcriptional termination sequence, and the like, that are naturally found within the DNA of a soybean genome are not considered to be isolated from the soybean genome so long as they are within the soybean genome. However, each of these components, and subparts of these components, would be “isolated” within the scope of this disclosure so long as the structures and components are not within the soybean genome. For the purposes of this disclosure, any transgenic nucleotide sequence, i.e., the nucleotide sequence of the DNA inserted into the genome of the cells of the soybean plant event MON87705 would be considered to be an isolated nucleotide sequence whether it is present within the plasmid used to transform soybean cells from which the MON87705 event arose, within the genome of the event MON87705, present in detectable amounts in tissues, progeny, biological samples or commodity products derived from the event MON87705. The nucleotide sequence or any fragment derived therefrom would therefore be considered to be isolated or isolatable if the DNA molecule can be extracted from cells, or tissues, or homogenate from a plant or seed or plant organ; or can be produced as an amplicon from extracted DNA or RNA from cells, or tissues, or homogenate from a plant or seed or plant organ, any of which is derived from such materials derived from the event MON87705. For that matter, the junction sequences as set forth at SEQ ID NOs: 1, 2 and 18, and nucleotide sequences derived from event MON87705 that also contain these junction sequences are considered to be isolated or isolatable, whether these sequences are present within the genome of the cells of event MON87705 or present in detectable amounts in tissues, progeny, biological samples or commodity products derived from the event MON87705.

A DNA molecule of the present invention may also be a recombinant DNA molecule. As used herein, the term recombinant means any agent (e.g. DNA, peptide etc.), that is, or results, however indirect, from human manipulation of a nucleic acid molecule.

A “probe” is an isolated nucleic acid to which is attached a conventional detectable label or reporter molecule, e.g., a radioactive isotope, ligand, chemiluminescent agent, or enzyme. Such a probe is complementary to a strand of a target nucleic acid, in the case of the present invention, to a strand of genomic DNA from soybean event MON87705 whether from a soybean plant or from a sample that includes DNA from the event. Probes according to the present invention include not only deoxyribonucleic or ribonucleic acids but also polyamides and other probe materials that bind specifically to a target DNA sequence and such binding can be used to detect the presence of that target DNA sequence.

“Primers” are isolated nucleic acids that are annealed to a complementary target DNA strand by nucleic acid hybridization to form a hybrid between the primer and the target DNA strand, and then extended along the target DNA strand by a polymerase, e.g., a DNA polymerase. Primer pairs of the present invention refer to their use for amplification of a target nucleic acid sequence, e.g., by the polymerase chain reaction (PCR) or other conventional nucleic-acid amplification methods.

Probes and primers are generally 11 nucleotides or more in length, preferably 15 nucleotides or more, more preferably 18 nucleotides or more, more preferably 20 nucleotides or more, more preferably 24 nucleotides or more, and most preferably 30 nucleotides or more. Such probes and primers hybridize specifically to a target sequence under high stringency hybridization conditions. Preferably, probes and primers according to the present invention have complete sequence similarity with the target sequence, although probes differing from the target sequence and that retain the ability to hybridize to target sequences may be designed by conventional methods.

Methods for preparing and using probes and primers are described, for example, in Molecular Cloning: A Laboratory Manual, 2nd ed., vol. 1-3, ed. Sambrook et al., Cold Spring Harbor Laboratory Press, Cold Spring Harbor, N.Y., 1989 (hereinafter, “Sambrook et al., 1989”); Current Protocols in Molecular Biology, ed. Ausubel et al., Greene Publishing and Wiley-Interscience, New York, 1992 (with periodic updates) (hereinafter, “Ausubel et al., 1992”); and Innis et al., PCR Protocols: A Guide to Methods and Applications, Academic Press: San Diego, 1990. PCR-primer pairs can be derived from a known sequence, for example, by using computer programs intended for that purpose such as Primer (Version 0.5, © 1991, Whitehead Institute for Biomedical Research, Cambridge, Mass.).

Primers and probes based on the flanking DNA and insert sequences disclosed herein can be used to confirm (and, if necessary, to correct) the disclosed sequences by conventional methods, e.g., by re-cloning and sequencing such sequences.

The nucleic acid probes and primers of the present invention hybridize under stringent conditions to a target DNA sequence. Any conventional nucleic acid hybridization or amplification method can be used to identify the presence of DNA from a transgenic event in a sample. Nucleic acid molecules or fragments thereof are capable of specifically hybridizing to other nucleic acid molecules under certain circumstances. As used herein, two nucleic acid molecules are said to be capable of specifically hybridizing to one another if the two molecules are capable of forming an anti-parallel, double-stranded nucleic acid structure. A nucleic acid molecule is said to be the “complement” of another nucleic acid molecule if they exhibit complete complementarity. As used herein, molecules are said to exhibit “complete complementarity” when every nucleotide of one of the molecules is complementary to a nucleotide of the other. Two molecules are said to be “minimally complementary” if they can hybridize to one another with sufficient stability to permit them to remain annealed to one another under at least conventional “low-stringency” conditions. Similarly, the molecules are said to be “complementary” if they can hybridize to one another with sufficient stability to permit them to remain annealed to one another under conventional “high-stringency” conditions. Conventional stringency conditions are described by Sambrook et al., 1989, and by Haymes et al., In: Nucleic Acid Hybridization, A Practical Approach, IRL Press, Washington, D.C. (1985). Departures from complete complementarity are therefore permissible, as long as such departures do not completely preclude the capacity of the molecules to form a double-stranded structure. In order for a nucleic acid molecule to serve as a primer or probe it need only be sufficiently complementary in sequence to be able to form a stable double-stranded structure under the particular solvent and salt concentrations employed.

As used herein, a substantially homologous sequence is a nucleic acid sequence that will specifically hybridize to the complement of the nucleic acid sequence to which it is being compared under high stringency conditions. Appropriate stringency conditions which promote DNA hybridization, for example, 6.0× sodium chloride/sodium citrate (SSC) at about 45° C., followed by a wash of 2.0×SSC at 50° C., are known to those skilled in the art or can be found in Current Protocols in Molecular Biology, John Wiley & Sons, N.Y. (1989), 6.3.1-6.3.6. For example, the salt concentration in the wash step can be selected from a low stringency of about 2.0×SSC at 50° C. to a high stringency of about 0.2×SSC at 50° C. In addition, the temperature in the wash step can be increased from low stringency conditions at room temperature, about 22° C., to high stringency conditions at about 65° C. Both temperature and salt may be varied, or either the temperature or the salt concentration may be held constant while the other variable is changed. In a embodiment, a nucleic acid of the present invention will specifically hybridize to one or more of the nucleic acid molecules set forth in SEQ ID NO: 1 and 2 or complements thereof or fragments of either under moderately stringent conditions, for example at about 2.0×SSC and about 65° C. In a particularly preferred embodiment, a nucleic acid of the present invention will specifically hybridize to one or more of the nucleic acid molecules set forth in SEQ ID NO:1 and SEQ ID NO: 2 or complements or fragments of either under high stringency conditions. In one aspect of the present invention, a marker nucleic acid molecule of the present invention has the nucleic acid sequence set forth in SEQ ID NO: 1 and SEQ ID NO: 2 or complements thereof or fragments of either. In another aspect of the present invention, a marker nucleic acid molecule of the present invention shares 80%, 81%, 82%, 83%, 84%, 85%, 86%, 87%, 88%, 89%, 90%, 912%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99% and 100% sequence identity with the nucleic acid sequence set forth in SEQ ID NO: 1 and SEQ ID NO: 2 or complement thereof or fragments of either. In a further aspect of the present invention, a marker nucleic acid molecule of the present invention shares 95% 96%, 97%, 98%, 99% and 100% sequence identity with the sequence set forth in SEQ ID NO: 1 and SEQ ID NO: 2 or complement thereof or fragments of either. SEQ ID NO: 1 and SEQ ID NO: 2 may be used as markers in plant breeding methods to identify the progeny of genetic crosses similar to the methods described for simple sequence repeat DNA marker analysis, in “DNA markers: Protocols, applications, and overviews: (1997) 173-185, Cregan, et al., eds., Wiley-Liss NY; all of which is herein incorporated by reference. The hybridization of the probe to the target DNA molecule can be detected by any number of methods known to those skilled in the art, these can include, but are not limited to, fluorescent tags, radioactive tags, antibody based tags, and chemiluminescent tags.

Regarding the amplification of a target nucleic acid sequence (e.g., by PCR) using a particular amplification primer pair, “stringent conditions” are conditions that permit the primer pair to hybridize only to the target nucleic-acid sequence to which a primer having the corresponding wild-type sequence (or its complement) would bind and preferably to produce a unique amplification product, the amplicon, in a DNA thermal amplification reaction.

The term “specific for (a target sequence)” indicates that a probe or primer hybridizes under stringent hybridization conditions only to the target sequence in a sample comprising the target sequence.

As used herein, “amplified DNA” or “amplicon” refers to the product of nucleic-acid amplification of a target nucleic acid sequence that is part of a nucleic acid template. For example, to determine whether the soybean plant resulting from a sexual cross contains transgenic event genomic DNA from the soybean plant of the present invention, DNA extracted from a soybean plant tissue sample may be subjected to nucleic acid amplification method using a primer pair that includes a primer derived from flanking sequence in the genome of the plant adjacent to the insertion site of inserted heterologous DNA, and a second primer derived from the inserted heterologous DNA to produce an amplicon that is diagnostic for the presence of the event DNA. The amplicon is of a length and has a sequence that is also diagnostic for the event. The amplicon may range in length from the combined length of the primer pairs plus one nucleotide base pair, preferably plus about fifty nucleotide base pairs, more preferably plus about two hundred-fifty nucleotide base pairs, and even more preferably plus about four hundred-fifty nucleotide base pairs. Alternatively, a primer pair can be derived from flanking sequence on both sides of the inserted DNA so as to produce an amplicon that includes the entire insert nucleotide sequence. A member of a primer pair derived from the plant genomic sequence may be located a distance from the inserted DNA molecule, this distance can range from one nucleotide base pair up to about twenty thousand nucleotide base pairs. The use of the term “amplicon” specifically excludes primer-dimers that may be formed in the DNA thermal amplification reaction.

Nucleic-acid amplification can be accomplished by any of the various nucleic-acid amplification methods known in the art, including the polymerase chain reaction (PCR). A variety of amplification methods are known in the art and are described, inter alia, in U.S. Pat. Nos. 4,683,195 and 4,683,202 and in PCR Protocols: A Guide to Methods and Applications, ed. Innis et al., Academic Press, San Diego, 1990. PCR amplification methods have been developed to amplify up to 22 kb of genomic DNA and up to 42 kb of bacteriophage DNA (Cheng et al., Proc. Natl. Acad. Sci. USA 91:5695-5699, 1994). These methods as well as other methods known in the art of DNA amplification may be used in the practice of the present invention. The sequence of the heterologous DNA insert or flanking sequence from soybean event MON87705 with seed samples deposited as ATCC PTA-9241 can be verified (and corrected if necessary) by amplifying such sequences from the event using primers derived from the sequences provided herein followed by standard DNA sequencing of the PCR amplicon or of the cloned DNA.

The amplicon produced by these methods may be detected by a plurality of techniques. One such method is Genetic Bit Analysis (Nikiforov, et al. Nucleic Acid Res. 22:4167-4175, 1994) where an DNA oligonucleotide is designed which overlaps both the adjacent flanking genomic DNA sequence and the inserted DNA sequence. The oligonucleotide is immobilized in wells of a microwell plate. Following PCR of the region of interest (using one primer in the inserted sequence and one in the adjacent flanking genomic sequence), a single-stranded PCR product can be hybridized to the immobilized oligonucleotide and serve as a template for a single base extension reaction using a DNA polymerase and labelled ddNTPs specific for the expected next base. Readout may be fluorescent or ELISA-based. A signal indicates presence of the insert/flanking sequence due to successful amplification, hybridization, and single base extension.

Another method is the Pyrosequencing technique as described by Winge (Innov. Pharma. Tech. 00:18-24, 2000). In this method an oligonucleotide is designed that overlaps the adjacent genomic DNA and insert DNA junction. The oligonucleotide is hybridized to single-stranded PCR product from the region of interest (one primer in the inserted sequence and one in the flanking genomic sequence) and incubated in the presence of a DNA polymerase, ATP, sulfurylase, luciferase, apyrase, adenosine 5′ phosphosulfate and luciferin. dNTPs are added individually and the incorporation results in a light signal which is measured. A light signal indicates the presence of the transgene insert/flanking sequence due to successful amplification, hybridization, and single or multi-base extension.

Fluorescence Polarization as described by Chen, et al., (Genome Res. 9:492-498, 1999) is a method that can be used to detect the amplicon of the present invention. Using this method an oligonucleotide is designed which overlaps the genomic flanking and inserted DNA junction. The oligonucleotide is hybridized to single-stranded PCR product from the region of interest (one primer in the inserted DNA and one in the flanking genomic DNA sequence) and incubated in the presence of a DNA polymerase and a fluorescent-labeled ddNTP. Single base extension results in incorporation of the ddNTP. Incorporation can be measured as a change in polarization using a fluorometer. A change in polarization indicates the presence of the transgene insert/flanking sequence due to successful amplification, hybridization, and single base extension.

TaqMan® (PE Applied Biosystems, Foster City, Calif.) is described as a method of detecting and quantifying the presence of a DNA sequence and is fully understood in the instructions provided by the manufacturer. Briefly, a FRET oligonucleotide probe is designed which overlaps the genomic flanking and insert DNA junction. The FRET probe and PCR primers (one primer in the insert DNA sequence and one in the flanking genomic sequence) are cycled in the presence of a thermostable polymerase and dNTPs. Hybridization of the FRET probe results in cleavage and release of the fluorescent moiety away from the quenching moiety on the FRET probe. A fluorescent signal indicates the presence of the flanking/transgene insert sequence due to successful amplification and hybridization.

Molecular Beacons have been described for use in sequence detection as described in Tyangi, et al. (Nature Biotech. 14:303-308, 1996) Briefly, a FRET oligonucleotide probe is designed that overlaps the flanking genomic and insert DNA junction. The unique structure of the FRET probe results in it containing secondary structure that keeps the fluorescent and quenching moieties in close proximity. The FRET probe and PCR primers (one primer in the insert DNA sequence and one in the flanking genomic sequence) are cycled in the presence of a thermostable polymerase and dNTPs. Following successful PCR amplification, hybridization of the FRET probe to the target sequence results in the removal of the probe secondary structure and spatial separation of the fluorescent and quenching moieties that results in the production of a fluorescent signal. The fluorescent signal indicates the presence of the flanking/transgene insert sequence due to successful amplification and hybridization.

Other described methods, such as microfluidics (US Patent Pub. 2006068398, U.S. Pat. No. 6,544,734) provide methods and devices to separate and amplify DNA samples. Optical dyes are used to detect and quantitate specific DNA molecules (WO/05017181). Nanotube devices (WO/06024023) that comprise an electronic sensor for the detection of DNA molecules or nanobeads that bind specific DNA molecules and can then be detected.

DNA detection kits can be developed using the compositions disclosed herein and the methods well known in the art of DNA detection. The kits are useful for the identification of soybean event MON87705 DNA in a sample and can be applied to methods for breeding soybean plants containing the appropriate event DNA. The kits may contain DNA primers or probes that are homologous or complementary to SEQ ID NO: 1 through SEQ ID NO: 5 or DNA primers or probes homologous or complementary to DNA contained in the transgene genetic elements of DNA. These DNA sequences can be used in DNA amplification reactions or as probes in a DNA hybridization method. The sequences of the genomic DNA and transgene genetic elements contained in MON87705 soybean genome are illustrated in FIG. 2; the transgene genetic element contained in the T-DNAs are organized as follows: the first T-DNA begins with the octopine left border sequence, followed by the first artificial gene comprised of the 35S enhancer from figwort mosaic virus (FMV), and promoter, intron, and leader sequence from the Arabidopsis thaliana Tsfl gene, which is upstream of the ShkG transit peptide fused to an optimized aroA-CP4, which is upstream of the 3′ UTR of the RbcS2 (E9) gene from Pisum sativum, followed by the second cassette which is comprised of the promoter and leader sequence from the Glycine max 7S alpha prime subunit of beta-conglycinin gene, which is upstream of the sense half of the inverted repeat containing sequences homologous to the Glycine max FAD2 and FATB genes, which is upstream of the nopaline right border sequence. The second T-DNA begins with the nopaline right border sequence, which is upstream of the antisense half of the inverted repeat containing sequences homologous to the Glycine max FAD2 and FATB genes, which is upstream of the 3′ UTR of the Gossypium barbadense (Sea island cotton) H6 gene, which is upstream of the octopine left border sequence. The primer molecules derived from these sequences can be used as part of a primer set that also includes a DNA primer molecule derived from the genome flanking the transgene insert of event MON87705 as presented in SEQ ID NO: 3 and SEQ ID NO: 4.

The present invention includes a soybean plant comprising a DNA molecule comprising a polynucleotide having a sequence that is or is complementary to a sequence selected from the group consisting of SEQ ID NOs: 1, 2 and 18. In another aspect, the present invention includes a soybean plant part, where the plant part comprises a polynucleotide having a sequence that is or is complementary to a sequence selected from the group consisting of SEQ ID NOs: 1, 2 and 18. In another aspect, the present invention includes progeny of a soybean plant, where the progeny comprises a polynucleotide having a sequence that is or is complementary to a sequence selected from the group consisting of SEQ ID NOs: 1, 2 and 18.

EXAMPLES Example 1 Transformation of Soybean A3525 with pMON95829 and Event Selection

The transgenic soybean plant MON87705 was generated by an Agrobacterium-mediated transformation of soybean cells with DNA fragments derived from pMON95829 (FIG. 1). The binary plant transformation vector, pMON95829 contains two plant transformation T-DNAs. Each T-DNA was flanked by right border (RB) and left border (LB) sequences at the ends of the T-DNAs. Post transformation screening of MON87705 identified a right border to right border co-integration of the two T-DNAs generating a two cassette insertion, one designed to express the aroA-CP4 gene from Agrobacterium tumefaciens imparting glyphosate tolerance and the other designed with an inverted repeat to trigger the RNAi based suppression of the endogenous FAD2 and FATB genes (SEQ ID NO: 7). The inverted repeat structure is not found in pMON95829, but is formed with a RB to RB co-integration of the two T-DNAs. This integration configuration yields a single transgenic locus containing both expression and suppression cassettes and is flanked by residual left border sequences (FIG. 2). The unique sequence generated at the RB:RB integration site is listed under SEQ ID NO: 18.

The T-DNAs are organized as follows: the first T-DNA begins with the octopine LB sequence, followed by the first artificial gene comprised of the 35S enhancer from figwort mosaic virus (FMV) and the promoter, intron, and leader sequence from the Arabidopsis thaliana Tsfl gene, which is upstream of the ShkG transit peptide fused to an optimized aroA-CP4, which is upstream of the 3′ UTR of the RbcS2 (E9) gene from Pisum sativum, followed by the second cassette which is comprised of the promoter and leader sequence from the Glycine max 7S alpha prime subunit of beta-conglycinin gene, which is upstream of the sense half of the inverted repeat containing sequences homologous to the Glycine max FAD2 and FATB genes, which is upstream of the nopaline RB sequence. The second T-DNA begins with the nopaline RB sequence, which is upstream of the antisense half of the inverted repeat containing sequences homologous to the Glycine max FAD2 and FATB genes, which is upstream of the 3′ UTR of the Gossypium barbadense (Sea island cotton) H6 gene, which is upstream of the octopine LB sequence.

Explants transformed with pMON95829 were obtained via Agrobacterium tumefaciens-mediated transformation. Plants were regenerated from transformed tissue. Approximately 955 R0 transformation events were produced and were tested for the presence of the two T-DNAs by Invader′ (Third Wave Technologies, Inc., Madison, Wis.). In addition, a PCR designed to identify the RB:RB configuration was used to select properly-assembled candidate events. R0 events demonstrating the proper co-integration of the T-DNAs were self-pollinated to generate R1 seed. The fatty acid composition of the R1 seed was determined by FAME-GC analysis. Based on these analyses, 48 events were carried forward to the R2 generation. Segregation of multi copy events and phenotypic characterization narrow the candidate event pool to 11 events by the R3 generation.

Detailed southern analysis designed to verify copy number, cassette intactness, locus and absence of undesired vector sequence was performed. In subsequent generations, field performance characteristics, as well as sequence flanking the insertion site for the remaining events, were also determined. One progeny line designated event MON87705 was selected based upon its overall fatty acid composition profile (Table 1), agronomic performance and molecular characteristics.

Example 2 Isolation of Flanking Sequences Using Inverse PCR

Sequences flanking the T-DNA insertion in MON87705 were determined using inverse PCR as described in Ochman et al., 1990 (PCR Protocols: A guide to Methods and Applications, Academic Press, Inc.) and by TAIL (Thermal Asymmetric InterLaced) PCR. Plant genomic DNA was isolated from both wild-type A3525 and the transgenic line from tissue grown under green house conditions. Frozen leaf tissue was ground by mortar and pestle with liquid nitrogen or mechanical grinding. A volume of 22 mL of extraction buffer was added to ˜1 g of ground leaf tissue and incubated at 65° C. for 1 hour. The CTAB extraction buffer consisted of 1.4M NaCl, 2% CTAB, 20 mM EDTA, and 100 mM Tris-HCl pH 8.0. Just prior to use, 0.02% beta-mercaptoethanol and 0.5 mg RNase A was added to the extraction buffer. The samples were extracted with 12 mL of phenol/chloroform/isoamyl alcohol (25:24:1) solution and then centrifuged at 4000×G for 10 minutes at 4° C. The supernatant was transferred to a new tube and the DNA was precipitated with 15 mL of isopropanol. After centrifugation at 4000×G for 10 minutes, the pellets were washed with 5 mL 70% ethanol. A final centrifugation at 4000×G for 5 minutes was performed; the pellets were air dried and then re-suspended in 300 μL of water.

An aliquot of DNA was subjected to TAIL PCR and a region of sequence adjacent to the insertion site was isolated and sequenced. Additionally an aliquot of DNA was digested with restriction endonucleases selected based upon restriction analysis of the T-DNA. After self-ligation of restriction fragments, PCR was performed using primers designed from the T-DNA sequence that would amplify sequences extending away from the 5′ and 3′ ends of the T-DNA. PCR products were separated by agarose gel electrophoresis and purified using a QIAGEN gel purification kit (Qiagen, Valencia, Calif.). The subsequent products were sequenced directly using standard sequencing protocols.

Extension of the initial flanking sequence extending away from the 5′ end of the T-DNA was performed using the Genomewalker™ kit (Clontech, Mountain View, Calif.). Standard protocol conditions were used and primers presented as SEQ ID NO: 19 and SEQ ID No: 20 were used in the nested PCR along with the supplied AP1 and AP2 primers. Reactions were run in duplicate and products were cloned and sequenced directly using standard sequencing protocols. Sequences were compared to the duplicate run, prior genomic sequences, and the 3′ flanking sequence to determine actual polymorphisms from PCR-derived errors. There is apparently a chromosomal duplication that occurred upon generation of the MON87705 event. This region of duplication (SEQ ID NO: 17) corresponds to position 1053 through 3422 of SEQ ID NO: 6 and is nearly identical to position 10682 through 13051 of SEQ ID NO: 6. We have determined that there are two polymorphisms between the repeat located on the 5′ end of the insert and the repeat from the 3′ end of the insert, with the 3′ end of the insert matching the original genomic sequence.

Using these methods, the identified 5′ flanking sequence of the insertion was presented as SEQ ID NO: 3 (see FIG. 2), and the 3′ flanking sequence was presented as SEQ ID NO: 4 (see FIG. 2). The portion of the inserted cassettes (SEQ ID NO: 7) from pMON95829 that was fully integrated into the A3525 genomic DNA is presented as SEQ ID NO: 5 (see FIG. 2).

Isolated sequences were compared to the T-DNA sequence to identify the flanking sequence and the co-isolated T-DNA fragment. Confirmation of the presence of the expression cassette was achieved by PCR with primers designed based upon the deduced flanking sequence data and the known T-DNA sequence. The A3525 wild type sequence corresponding to the same region in which the T-DNA was integrated in the transformed line was isolated using primers designed from the flanking sequences in MON87705. The flanking sequences in MON87705 and the A3525 wild type sequence were analyzed against multiple nucleotide and protein databases. This information was used to examine the relationship of the transgene to the plant genome and to look at the insertion site integrity. The flanking sequence and wild type sequences were used to design primers for TaqMan endpoint assays used to identify the events and determine zygosity as described in Example 3.

Example 3 Event-specific Endpoint TaqMan and Zygosity Assays

The methods used to identify event MON87705 in a sample are event-specific endpoint TaqMan PCR assays for which examples of conditions are described in Table 2 and Table 3. The first set of DNA primers that may be used in the endpoint assays are primers SQ20129 (SEQ ID NO: 8), SQ20130 (SEQ ID NO: 9) and 6FAM™ labeled primer PB10043 (SEQ ID NO: 10). The second set of DNA primers that may be used in the endpoint assays are primers SQ21928 (SEQ ID NO:11), SQ20901 (SEQ ID NO:12), and 6FAM™ labeled primer PB10164 (SEQ ID NO:13). 6FAM™ is a fluorescent dye product of Applied Biosystems (Foster City, Calif.) attached to the DNA primers. For TaqMan MGB (Minor Groove Binding) probes, the 5′exonuclease activity of Taq DNA polymerase cleaves the probe from the 5′-end, between the fluorophore and quencher. When hybridized to the target DNA strand, quencher and fluorophore are separated enough to produce a fluorescent signal.

SQ20129 (SEQ ID NO: 8) and SQ20130 (SEQ ID NO: 9) when used as described with PB10043 (SEQ ID NO: 10) produce a DNA amplicon that is diagnostic for event MON87705 DNA. SQ21928 (SEQ ID NO: 11) and SQ20901 (SEQ ID NO: 12) when used as described with PB10164 (SEQ ID NO: 13) produce a DNA amplicon that is also diagnostic for event MON87705 DNA. The controls for these analyses should include a positive control from soybean known to contain event MON87705 DNA, a negative control from non-transgenic soybean and a negative control that contains no template DNA. Similar assays can be designed for SEQ ID 18

These assays are optimized for use with an Applied Biosystems GeneAmp PCR System 9700, Stratagene Robocycler, MJ Engine, Perkin-Elmer 9700 or Eppendorf Mastercycler Gradient thermocycler. Other methods and apparatus may be known to those skilled in the art to produce amplicons that identify the event MON87705 DNA.

DNA amplification in a Stratagene Robocycler, MJ Engine, Perkin-Elmer 9700, Eppendorf Mastercycler Gradient thermocycler, Applied Biosystems GeneAmp PCR System 9700 or MJ Research DNA Engine PTC-225 thermal cycler is performed using the following cycling parameters. When running the PCR in the Eppendorf Mastercycler Gradient or MJ Engine, the thermocycler should be run in the calculated mode. When running the PCR in the Perkin-Elmer 9700, the thermocycler is run with the ramp speed set at maximum.

Determining zygosity for event MON87705 in a sample was done using an event-specific zygosity endpoint TaqMan PCR assay for which examples of conditions are described in Table 4 and Table 5. The DNA primers used in the zygosity assay are primers SQ20901 (SEQ ID NO: 12), SQ21928 (SEQ ID NO: 11), SQ21905 (SEQ ID NO: 15), 6FAM™ labeled primer PB10164 (SEQ ID NO: 13) and VIC™ labeled primer PB10335 (SEQ ID NO: 14). 6FAM™ and VIC™ are fluorescent dye products of Applied Biosystems (Foster City, Calif.) attached to the DNA primers.

SQ20901 (SEQ ID NO: 12) and SQ21928 (SEQ ID NO: 11) when used in these reaction methods with PB10164 (SEQ ID NO: 13) produce a DNA amplicon that is diagnostic for event MON87705 DNA. The controls for this analysis should include a positive control from soybean containing event MON87705 DNA, a negative control from non-transgenic soybean and a negative control that contains no template DNA. SQ21928 (SEQ ID NO: 11) and SQ21905 (SEQ ID NO: 15) when used in these reaction methods with PB10335 (SEQ ID NO: 14) produce a DNA amplicon that is diagnostic for the wild type allele and contains SEQ ID NO: 16 in its entirety. Heterozygosity is determined by the presence of both amplicons demonstrated by the liberation of fluorescent signal from both probes PB10164 and PB10335.

These assays are optimized for use with an Applied Biosystems GeneAmp PCR System 9700, Stratagene Robocycler, MJ Engine, Perkin-Elmer 9700 or Eppendorf Mastercycler Gradient thermocycler. Other methods and apparatus known to those skilled in the art that produce amplicons that identify the event MON87705 DNA is within the skill of the art.

Example 4 Identification of Event MON87705 in a Given Soybean Sample

The following example describes how one may identify the presence or absence of MON87705 event in a given soybean sample.

DNA event primer pairs are used to produce an amplicon diagnostic for soybean event MON87705. An amplicon diagnostic for MON87705 comprises at least one junction sequence: SEQ ID NO: 1, SEQ ID NO: 2 or SEQ ID NO: 18. SEQ ID NO: 1 (FIG. 2) is a nucleotide sequence corresponding to the junction of the 5′ flanking sequence (positions 3413 through 3422 of SEQ ID NO: 6, see FIG. 2) and the integrated border of the insertion (positions 3423 through 3433 of SEQ ID NO: 6, see FIG. 2). SEQ ID NO: 2 (see FIG. 2) is a nucleotide sequence corresponding to the junction of the integrated border of the insertion (positions 10664 through 10673 of SEQ ID NO: 6, see FIG. 2) and the 3′ flanking sequence (positions 10674 through 10683 of SEQ ID NO: 6, see FIG. 2). SEQ ID NO: 18 is a nucleotide sequence corresponding to the right border to right border junction (positions 9230 to 9335 of SEQ ID NO: 6) generated upon the cointegration of the two pMON95829 T-DNAs to yield event MON87705

Event primer pairs that will produce a diagnostic amplicon for MON87705 include primer pairs based upon the flanking sequences and the inserted cassettes. To acquire a diagnostic amplicon in which at least 11 nucleotides of SEQ ID NO: 1 is found, one would design a forward primer based upon SEQ ID NO: 3 from bases 1 through 3448 and a reverse primer based upon the inserted cassette, SEQ ID NO: 5 from positions 10 through 7251. To acquire a diagnostic amplicon in which at least 11 nucleotides of SEQ ID NO: 2 is found, one would design a forward primer based upon the inserted cassette, SEQ ID NO: 5, from positions 1 through 7241 and a reverse primer based upon the 3′ flanking sequence, SEQ ID NO: 4, from bases 10 through 2515. For practical purposes, one should design primers which produce amplicons of a limited size range, preferably between 200 to 1000 bases. Smaller sized amplicons in general are more reliably produced in PCR reactions, allow for shorter cycle times and can be easily separated and visualized on agarose gels or adapted for use in endpoint TaqMan-like assays. In addition, amplicons produced using said primer pairs can be cloned into vectors, propagated, isolated and sequenced or can be sequenced directly with methods well established in the art. Any primer pair derived from the combination of SEQ ID NO: 3 and SEQ ID NO: 5 or the combination of SEQ ID NO: 4 and SEQ ID NO: 5 that are useful in a DNA amplification method to produce an amplicon diagnostic for MON87705 or progeny thereof is an aspect of the present invention. Any single isolated DNA polynucleotide primer molecule comprising at least 11 contiguous nucleotides of SEQ ID NO: 3, or its complement that is useful in a DNA amplification method to produce an amplicon diagnostic for MON87705 or progeny thereof is an aspect of the present invention. Any single isolated DNA polynucleotide primer molecule comprising at least 11 contiguous nucleotides of SEQ ID NO: 4, or its complement that is useful in a DNA amplification method to produce an amplicon diagnostic for MON87705 or progeny thereof is an aspect of the present invention. Any single isolated DNA polynucleotide primer molecule comprising at least 11 contiguous nucleotides of SEQ ID NO: 5, or its complement that is useful in a DNA amplification method to produce an amplicon diagnostic for MON87705 or progeny thereof is an aspect of the present invention.

An example of the amplification conditions for this analysis is illustrated in Table 6 and Table 7. However, any modification of these methods or the use of DNA primers homologous or complementary to SEQ ID NO: 3 or SEQ ID NO: 4 or DNA sequences of the genetic elements contained in the transgene insert (SEQ ID NO: 5) of MON87705 that produce an amplicon diagnostic for MON87705, is within the art. A diagnostic amplicon comprises a DNA molecule homologous or complementary to at least one transgene/genomic junction DNA listed under SEQ ID NO: 1, 2 and 18, or a substantial portion thereof.

An analysis for event MON87705 plant tissue sample should include a positive tissue control from event MON87705, a negative control from a soybean plant that is not event MON87705, for example, but not limited to A3525, and a negative control that contains no soybean genomic DNA. A primer pair that will amplify an endogenous soybean DNA molecule will serve as an internal control for the DNA amplification conditions. Additional primer sequences can be selected from SEQ ID NO: 3, SEQ ID NO: 4, or SEQ ID NO: 5 by those skilled in the art of DNA amplification methods, and conditions selected for the production of an amplicon by the methods shown in Table 6 and Table 7 may differ, but result in an amplicon diagnostic for event MON87705 DNA. The use of these DNA primer sequences with modifications to the methods of Table 6 and Table 7 are within the scope of the invention. The amplicon produced by at least one DNA primer sequence derived from SEQ ID NO: 3, SEQ ID NO: 4 or SEQ ID NO: 5 that is diagnostic for MON87705 is an aspect of the invention.

DNA detection kits that contain at least one DNA primer derived from SEQ ID NO: 3, SEQ ID NO: 4 or SEQ ID NO: 5, that when used in a DNA amplification method, produces a diagnostic amplicon for MON87705 or its progeny is an aspect of the invention. A soybean plant or seed, wherein its genome will produce an amplicon diagnostic for MON87705 when tested in a DNA amplification method is an aspect of the invention. The assay for the MON87705 amplicon can be performed by using an Applied Biosystems GeneAmp PCR System 9700, Stratagene Robocycler, MJ Engine, Perkin-Elmer 9700 or Eppendorf Mastercycler Gradient thermocycler or any other amplification system that can be used to produce an amplicon diagnostic of MON87705 as shown in Table 7.
